Evaluation of Posterior Fossa Brain Tumors in Kerman from 1375 through 1380

Posterior fossa in cranium consists of cerebellum, brain stem, cranial nerve, fourth ventricle and vertebrobasal artery tree. Posteriar fossa tumors are one of the common brain neoplasms especially in children. To determine the clinicodemographic features of these tumors, a cross-sectional study in Kerman was designed and implemented. 386 cases of brain tumors were evaluated from 1375 through 1380 and 70 were posterior fassa tumors. 36 cases were female and 34 male. Mean age was 23.1+18.5 years and ages under 20 years old were the most frequent. Astrocytoma had 22 (31.4%) patients, medolloblastoma 18 (25.7%), meningioma 9 (129%), Acostic neuroma 9 (12.9%), Epidermoid tumor 6 (8.6%), Hemangioblastoma 2 (2.9%), Epandymoma, Oligodendroglioma, Plexus chroid papiloma, and Dermoid tumors each had one case (1.4%); Headache was the most common complaint. Astrocytoma and Medolloblastoma occured in childhood and adolescence. Findings suggested that posterior fassa tumors were common in children, which is in line with previous studies.
